Dedicated 5V compact fan

The Noctua NF-A4x10-5V is a 40mm case fan built for 5V operation. It runs at 4500 RPM and delivers 8.2 m³/h of airflow with a static pressure of 1.78 mm H2O. The SSO2 bearing and Smooth Commutation Drive provide quiet performance at 17.9 dBA.

Buyers restricted to 5V headers

This fan suits systems that only offer a 5 volt three-pin header and need a low-profile 10mm frame. Builders who need higher airflow or PWM speed regulation will need a different model.

5V voltage requirement

The single specification that decides fit is the 5V operating voltage; the fan draws 0.05 A and 0.25 W from a three-pin connector. Confirm your board or controller supplies 5V before purchase.

この商品に関する質問

What does the 3-pin 5V connector limit for speed control?

The 3-pin 5V connector allows voltage-based speed regulation but lacks a PWM wire for duty-cycle control.

What clearance does the 40 x 40 x 10 mm frame require?

It needs a 40 mm square mounting hole pattern and 10 mm depth behind the frame for the motor body.

How is the fan secured and which orientation step is often missed?

Four corner screws hold the 40 mm frame; the airflow arrow on the frame must point toward the heatsink or exhaust path.
